System and method for independent font substitution of string characters

Abstract

Various embodiments of a system and method for independent font substitution of string characters are described. The system and method for independent font substitution may include a font substitution component configured to receive a descriptor item that may include a text string that includes multiple characters, metrics associated with characters of the text string, and / or a preferred font for one or more of the characters. For a particular character, if the preferred font is available, the font substitution component may use a glyph from the preferred font to render a particular character. In other cases, if a font of the set of safe fonts includes a glyph that matches the particular character, the font substitution component may use that glyph to resolve the particular character. The font substitution component may generate a resolved text string includes such glyphs and scale the size of the glyphs according to the aforementioned metrics.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The present invention is directed to font substitution. More particularly, it is directed to substituting fonts of string characters within computing environments.[0003]2. Description of the Related Art[0004]In modern computing, the transfer of documents or files between computer systems is a common occurrence. For instance, electronic mail messages (“emails”) as well as email attachments (e.g., additional files or documents) are transferred between various users of the Internet and World Wide Web. In another example, documents and / or files are transferred between computer systems via a local area network (LAN) or via physical memory medium (e.g., compact disc or flash memory). In many cases, documents transferred between computer systems contain text or text-based information. To facilitate the rendering and display of text, formatting information is typically provided within documents that contain textual information. One type of form...

Benefits of technology

[0006]Various embodiments of a system and method for independent font substitution of string characters are described. The system and method for independent font substitution may include a font substitution component configured to receive a descriptor item that may in some embodiments include a text string that includes multiple characters, metrics associated with the text string and/or individual characters of the text string, and/or a preferred font for one or more of the characters. For each character of the text string, the font substitution component may be configured to determine whether the particular character's preferred font is available (e.g., determine whether the font is installed on the local computer system). If the font is available, the font substitution component may use a glyph from the preferred font to render a particular character. In other cases, such as when a character's preferred font is not available, the font su

Problems solved by technology

Accordingly, while one computer system may be able to correctly display text according to a particular font, another computer system that has a different set of installed fonts may not be able to correctly display the text according to the particular font.
